New calling cards always receive short messages from banks.

What you want to ask is why the new calling card always receives short messages from the bank. 1. The original owner used this mobile phone number to handle the loan business in the bank. The mobile phone number was bound to the credit card by the old user, but it was not unbound from the credit card when the mobile phone number was cancelled.

2. Banks or their partners send information through APP software. The new mobile phone number is an account whose mobile phone number is mistaken for a registered account by APP software, and will continue to send text messages.
